all-or-none law - (neurophysiology) a nerve impulse resulting from a weak stimulus is just as strong as a nerve impulse resulting from a strong stimulus

principle, rule - a rule or law concerning a natural phenomenon or the function of a complex system; "the principle of the conservation of mass"; "the principle of jet propulsion"; "the right-hand rule for inductive fields"

Bernoulli's law, law of large numbers - (statistics) law stating that a large number of items taken at random from a population will (on the average) have the population statistics

Benford's law - a law used by auditors to identify fictitious populations of numbers; applies to any population of numbers derived from other numbers; "Benford's law holds that 30% of the time the first non-zero digit of a derived number will be 1 and it will be 9 only 4.6% of the time"

Bose-Einstein statistics - (physics) statistical law obeyed by a system of particles whose wave function is not changed when two particles are interchanged (the Pauli exclusion principle does not apply)

Coulomb's Law - a fundamental principle of electrostatics; the force of attraction or repulsion between two charged particles is directly proportional to the product of the charges and inversely proportional to the distance between them; principle also holds for magnetic poles

Dalton's law of partial pressures, law of partial pressures, Dalton's law - (chemistry and physics) law stating that the pressure exerted by a mixture of gases equals the sum of the partial pressures of the gases in the mixture; the pressure of a gas in a mixture equals the pressure it would exert if it occupied the same volume alone at the same temperature

distribution law - (chemistry) the total energy in an assembly of molecules is not distributed equally but is distributed around an average value according to a statistical distribution

equilibrium law, law of chemical equilibrium - (chemistry) the principle that (at chemical equilibrium) in a reversible reaction the ratio of the rate of the forward reaction to the rate of the reverse reaction is a constant for that reaction

Fechner's law, Weber-Fechner law - (psychophysics) the concept that the magnitude of a subjective sensation increases proportional to the logarithm of the stimulus intensity; based on early work by E. H. Weber

Fermi-Dirac statistics - (physics) law obeyed by a systems of particles whose wave function changes when two particles are interchanged (the Pauli exclusion principle applies)

Kirchhoff's laws - (physics) two laws governing electric networks in which steady currents flow: the sum of all the currents at a point is zero and the sum of the voltage gains and drops around any closed circuit is zero

law of averages - a law affirming that in the long run probabilities will determine performance

law of diminishing returns - a law affirming that to continue after a certain level of performance has been reached will result in a decline in effectiveness

law of effect - (psychology) the principle that behaviors are selected by their consequences; behavior having good consequences tends to be repeated whereas behavior that leads to bad consequences is not repeated

law of gravitation, Newton's law of gravitation - (physics) the law that states any two bodies attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

By a Law of Nature with us, there is a constant attraction to the South; and, although in temperate climates this is very slight -- so that even a Woman in reasonable health can journey several furlongs northward without much difficulty -- yet the hampering effect of the southward attraction is quite sufficient to serve as a compass in most parts of our earth.

And as he thought it an indispensable duty, enjoined both by the Christian law, and by the law of nature itself; so was it withal so pleasant, that if any duty could be said to be its own reward, or to pay us while we are discharging it, it was this.

Six chapters are: legal education in continental Europe; the law of nature in European courts; legal education in England; the law of nature in English courts; legal education in the United States; the law of nature in American courts.
